One of the reasons I'm able to write books and still carry on with other work is that I do my best writing between 5am and midday.

The system isn't working for most people and never has worked for most women.

Writing a book is like running a marathon. You need to be fit to do it, mentally and, as far as possible, physically.

It is, after all, absurd that in 2017 women are still at best second-class citizens.

We are all impacted by the failings of a news media that almost always chooses which stories to cover according to the priorities and perspectives of white men with private educations.

Studies show that women seeking power tend to be punished for doing so, because it goes against cultural bias. Women are expected to be likeable and pliant. We are also trained to expect any success we attain to come to us through men - by pleasing men, as good employees, good partners.

It's not enough to vent about what you don't like on social media. I would ask everyone who can, men included, to get involved in an organisation actively working for gender equality.
